Been trading long enough to know that RSI is one of those tools everyone talks about but most people use wrong. The real edge isn't just knowing what RSI is—it's knowing when to actually trust it.

Let me share a quick RSI cheat sheet that's saved me countless times. RSI measures momentum from 0 to 100, and the basic zones everyone knows are above 70 (overbought) and below 30 (oversold). But here's the thing—blindly shorting at 70 or buying at 30 will drain your account fast.

The real skill is understanding context. In a strong uptrend, RSI sitting at 70 isn't a sell signal—it's actually telling you the trend is healthy. That's when oversold readings become your best buy-the-dip opportunities. Flip that to a downtrend and you're looking for rallies to short, not dips to buy.

Divergences are where RSI actually gets interesting. I've caught some of my best reversals by watching for price making a higher high while RSI makes a lower high. That disconnect usually means the move is running out of steam. Same logic with bullish divergences—price lower but RSI higher. Just make sure you're looking at higher timeframes to avoid getting faked out by noise.

One pattern that works consistently is the swing failure setup. When RSI crosses 30 but immediately bounces back above it without breaking lower, that's often a solid bullish signal. Bearish version is the same thing at 70. Pair these with actual support and resistance levels and you've got something worth trading.

Volume is the confirmation I never skip. An RSI signal without volume backing it up is just noise. And trendlines on RSI itself? They work. Draw them like you would on price, and breakouts usually signal something real is happening.

The RSI cheat sheet I keep coming back to: use it for reversals when the market is ranging, use it for pullback entries when you're in a trend, combine it with moving averages or MACD for extra confirmation, and always respect support and resistance zones. That's basically it.

Most traders overcomplicate this. RSI is simple—the hard part is staying disciplined and not trading every signal that pops up. Set your alerts, wait for the setups that actually match your strategy, and let the winning trades come to you.
